Description
The AP1688 is a high performance AC/DC PFC and constant current
controller for universal mains LED driver applications. The device is a
buck controller which operates as a boundary conduction mode
(BCM) to achieve high efficiency and easy EMI.
An open loop algorithm is adopted in the AP1688, which will make the
system achieve excellent line and load regulations with high PF for
universal mains input.
The AP1688 features fast start-up, low start-up current, low operation
current and high efficiency. It also has rich protection features
including over voltage, short and open circuit, over current, over
temperature protection.
The AP1688 is available in SO-8 package.
